Frequently Asked Questions
What is the difference between adding and multiplying fractions?▾
To add fractions you need a common denominator first. To multiply fractions you simply multiply numerators together and denominators together — no common denominator needed.
What is a mixed number?▾
A mixed number combines a whole number and a proper fraction, e.g. 1½. It is an alternative way to write improper fractions where the numerator exceeds the denominator.
Can I calculate with negative fractions?▾
Yes — enter a negative numerator to represent a negative fraction.
